- 通过客观指标与主观评分综合评估编码器性能。
- 发现压缩率与听感保真度存在权衡关系。
- 适合音频工程、音源制作等需要选型的场景。
音频的感知质量是听觉准确性与听众感知音质的结合，体现人类对音频媒体准确度、可懂度和保真度的反应。当前数字音频存储广泛依赖音频压缩编码器，其质量直接影响听感体验。本文认为，在选择音频编码器时，用户不应仅关注压缩效率，还应考量其声学感知质量特性。我们基于编码器性能测量、可视化分析及PEAQ评分，评估了多个常用音频压缩编码器在压缩性能与听觉感知质量方面的表现。结果揭示了数字音频压缩技术对感知质量的影响机制，为用户选择数字音频压缩方案提供决策依据。
原文摘要 · Abstract (English)
Perceptual quality of audio is the combination of aural accuracy and listener-perceived sound fidelity. It is how humans respond to the accuracy, intelligibility, and fidelity of aural media. Today this fidelity is also heavily influenced by the use of audio compression codecs for storing aural media in digital form. We argue that, when choosing an audio compression codec, users should not only look at compression efficiency but also consider the sonic perceptual quality properties of available audio compression codecs. We evaluate several commonly used audio compression codecs in terms of compression performance as well as their sonic perceptual quality via codec performance measurements, visualizations, and PEAQ scores. We demonstrate how perceptual quality is affected by digital audio compression techniques, providing insights for users in the process of choosing a digital audio compression scheme.
